Is it possible to assign a constant temperature at interface(and interface_shadow) while coupled boundary condition is assigned for both.
In my case, I assigned a fixed temperature in solid cell zone, but interface temperature comes out much higher than this value. Somebody help please.

Hi, I am having some issues with conjugate heat transfer. How did you create coupled walls?

I think , wall boundary condition should be used for interface in the pre-processor, then fluent will generate itself interface name_shadow boundary. You will see then coupled BC option for both and same should be used for conjugate effects.

what BC did you give for fluid zone?

At both fluid side and solid side interfaces, coupled BC is used. In cell zone conditions, for solid zone, I used fixed temperature, while for fluid zone, I did not specify any thing there. I used as usual BCs for fluid zone boundaries.
I guess its not possible to assign constant temperature at interface in conjugate case. We use coupled BCs there and its temperature will vary throughout.
